Chapter 18, Problem 42E

Interpretation Introduction

Interpretation:

The expression for the equilibrium constant of the reaction ${\text{NH}}_{\text{4}}\text{HS}\left(\text{s}\right)\rightleftharpoons {\text{ NH}}_{\text{3}}\left(\text{g}\right){\text{ +H}}_{\text{2}}\text{S}\left(\text{g}\right)$ is to be stated.

Concept introduction:

The equilibrium is a state of the chemical reaction in which the rate of the forward reaction and the rate of the backward reaction become the same. There is no net change in the concentration of reactants and products at the equilibrium condition.
